I do check mine with a digital torque adapter. That how found out how lousy HFT torque wrenches were. One was nearly double the torque setting before it clicked. No wonder I was snapping bolts
Also you should unload the torque wrenches when you not using them as leaving them loaded can cause the calibration to become un-calibrated.
I never buy a clickable setting torque wrench. Like StarTech said, you must dial back to 0 when done. I just buy the old school beam style jobs that work for decades. Pick them up at garage sales or facetrash market place for cheap.
